In the Nicomachean Ethics Aristotle often focused on finding the mean between two extremes of any particular subject; whether it be justice, courage, wealth and so forth. For example, courage is a mean between two feelings (fear and confidence) and an action (the courageous act). Too much fear or too little confidence leads to cowardice, and too little fear or too much confidence can lead to rash, foolish choices. Aristotle says that finding this middle ground is essential to reaching eudemonia, otherwise known as the golden mean.

Quite simply put, hate would be on one end of the etreme of a scale that has love in the middle and all consuming obsession/addiction on the other.
